On October 31, 1984, EPA published a notice in the Federal Register withdrawing proposed standards for radionuclide emissions from four sources: (1) DOE facilities, (2) NRC-licensed facilities and non-DOE Federal facilities, (3) underground uranium mines and (4) elemental phosphorus plants. This Background Information Document supports the Agency's final actions on radionuclides. Volume I is an integrated risk assessment. It addresses historical and current regulatory programs and strategies, hazard identifications (health effects), radionuclide emissions, reduction of dose and risk, movement of radionuclides through environmental pathways, radiation dosimetry, and estimating the risk of health effects resulting from radionuclide air emissions. Volume II examines the source categories and presents the following information for each category: a general description of the source category, a brief description of the processes that lead to the emissions of radionuclides into air, a summary of emissions data, and estimates of the radiation doses and health risks to both individuals and populations.
